I believe the carrot and stick metaphor which humans frequently refer to is apt here. Simply asking people to speak and provide information will not always work. Frequently they need the motivation that comes from the promise of reward or the threat of punishment. Simply asking Minato-san to participate more is unlikely to be sufficient to make him feel much pressure to answer, and people under pressure also tend to make mistakes over time.
So while my vote is not yet final, which should be obvious as any of us can unvote at any time prior to days end and change our minds, this is a direct challenge to participate more so I can gain more information to begin theorizing about his allegiance. He could very likely convince me that he is not a member of Strega, or at least a less likely candidate than some others, or he may convince me that he is a prime suspect. We shall see.
But essentially, as I do not possess a proverbial carrot with which to tempt people, I must resort to the stick. Though I suppose one could say the proverbial carrot in this instance is unvoting. Perhaps this metaphor doesn't translate quite as directly as I would like after all.
